Picnik

I just tried out a new free photo editing software program.  Picnik is a web based software program.  It was fast and easy to use.  I've been using picasa and it works just fine.  I tried paint.net a few years ago (liked it).  I would also like to try photoscape.  I don't do anything fancy with my photos.  I usually deal in brightness (fill light), contrast, and colors.  The important thing to me is that the software be easy to use.

Here's a picture you might recognize, but I did a little work on it in Picnik:
